... ELECTRONIC SIGNATURE – Manufacturer Code: 20h – Device Code: B4 DESCRIPTION The M27C405 Mbit EPROM offered in the OTP (one time programmable) range ideally suited for microprocessor systems requiring large programs, in the application where the contents is stable and needs to be programmed only one time and is organised as 524,288 by 8 bits ...

... Standby Mode A1 The M27C405 has a standby mode which reduces A2 the active current from 30mA to 100 A. The A3 M27C405 is placed in the standby mode by apply- ing a CMOS high signal to the E input. When in the standbymode, the outputs are in a high impedance state, independent of the G input ...

... Datais introducedby selectively program- ming ’0’s into the desired bit locations. Although only ’0’s will be programmed, both ’1’s and ’0’s can be present in the data word. The M27C405 is in the programming mode when V 12.75V ...

... Programming of multiple M27C405s in parallelwith different data is also easily accomplished. Except for E, all like inputs including G of the parallel M27C405 may be common. A TTL low level pulse appliedto a M27C405’sE input,with V will program that M27C405. A high level E input inhibits the other M27C405s from being pro- grammed ...
